Question

which factor is an aspect of social health?
how others react to you
how you meet demands in everyday life
how you get creative
how you express your feelings in a personal journal

Explanation:

Social health involves interactions with others. "How others react to you" directly relates to social interactions. "How you meet demands in everyday life" is more about general coping (could be related to mental/emotional health). "How you get creative" is related to personal skills. "How you express your feelings in a personal journal" is more of a personal/emotional outlet (not social interaction - based).

Answer:

how others react to you
